BNC 50 Ω RF Connectors Guide: Types, Structure, and Uses Explained
What are BNC 50 Ω RF Connectors?
BNC (Bayonet Neill–Concelman) 50 Ω RF connectors are commonly used in video, communication, and measurement equipment due to their good frequency range (DC to 2 GHz), compact size, and light weight. They have a 50 Ω impedance and use a bayonet locking system for easy connection.
BNC RF connectors come in 50 Ω and 75 Ω versions. The 50 Ω connector is typically used for power transmission in radio equipment, while the 75 Ω connector is mainly used for video and audio signal transmission in TV receivers.

Trivia: Compatible Cable Types
- MIL Standard Cables: Also called Mil-Spec, these cables meet strict US military standards for performance and durability. Often starting with "RG" (Radio Guide), they are essential in high-demand areas like defense, aerospace, and telecommunications.
- Micro Coaxial Cables: These ultra-thin cables are designed to connect to miniature RF connectors like U.FL. They ensure signal integrity in space-constrained electronic devices such as smartphones, laptops, and medical equipment.
- Semi-Flexible Coaxial Cables: With moderate flexibility, these cables can bend and hold their shape while offering strong shielding and low signal loss, making them ideal for precise routing in telecommunications, test equipment, and internal electronics.
- Semi-Rigid Coaxial Cables: Made from a seamless metal tube, these cables provide superior shielding and minimal signal loss. Their rigid design ensures stable performance in critical applications like military systems, high-frequency instruments, aerospace, and microwave assemblies.
BNC 50 Ω RF Connector Features
Coupling Method
The Bayonet lock method is an easy way to connect and disconnect without threading. Simply align the plug with the jack’s guide, rotate the ring slightly to lock it in place, and the internal spring will hold it securely. To remove it, just turn it in the opposite direction. Because it’s held by a screw, the connector cannot be pulled out by just tugging on the cable.
Trivia: The Origin of BNC
The name BNC is often thought to come from "Bayonet" and "Neill Concelman," the connector manufacturer. However, there are various theories, including interpretations like BayoNet Connector, Baby-series N Connector, and British National Connector.
Many Uses
Thanks to its low cost, good frequency response, and small size, the BNC connector is widely used across various fields, including measurement, communication, video signals, office equipment, mobile devices, and factory automation. It is also used as an upgraded version of RCA terminals for simple signal transmission.
Impedance
BNC connectors come in 50 Ω and 75 Ω types. The 50 Ω version is used for transmitting power in radio equipment, while the 75 Ω version is used for video and audio signals. If a 75 Ω cable is connected to a 50 Ω connector, it works for frequencies up to 200 MHz. For higher frequencies, BNC 75 Ω connectors are recommended.

BNC 50 Ω RF Connector FAQs
QCan BNC and 75Ω types be connected?
QCan BNC and 75Ω types be connected?
Yes, you can connect them. For example, a BNC75Ω jack, a 50Ω BNC plug, and a 75Ω cable can be used together. However, it’s only suitable for frequencies below 200 MHz, so matching impedances is recommended.

QHow can I reduce the cost of the cable assembly?
QHow can I reduce the cost of the cable assembly?
We offer crimp-type connectors, which require a crimping tool but are lighter and more affordable than clamping-type connectors. If you'd like, we can process the cable assembly for you, so no crimping tool is needed.
QAre there connectors that provide a stronger cable connection?
QAre there connectors that provide a stronger cable connection?
Clamping-type connectors provide a more secure connection than crimp-type ones. The "Z" series, which uses a triple chuck method, has a clamping nut that tightly grips the cable jacket, making disconnection more difficult.
QDo you offer plugs that don’t require soldering or crimping tools?
QDo you offer plugs that don’t require soldering or crimping tools?
Yes, we have one-touch tightening plugs that don’t require soldering or crimping tools. These are convenient for on-site processing, as soldering is time-consuming and crimping tools can be expensive for small batches.
QCan I use a right angle connector if no compatible cable is available?
QCan I use a right angle connector if no compatible cable is available?
If a right-angle connector isn’t compatible with your cable, you can often use a straight connector combined with a right-angle adaptor.
QDo you have waterproof connectors?
QDo you have waterproof connectors?
Yes, we offer waterproof BNC connectors, with varying IP ratings depending on the product. The waterproofing features include:
1. Mating part waterproofing
2. Cable attachment point waterproofing
3. O-ring waterproofing at the cable attachment point
4. O-ring waterproofing at the flange mount
